Service/model retirement
Firebase Apple SDK Authentication email action links Dynamic Links migration obsolete domain
Authentication emails open a dead/incorrect deep-link route after SDK migration.
Agent Quick Fix
Repair against the current Firebase Apple SDK contract, then keep the change narrow and source-backed.
Product: Firebase Apple SDK
Current-contract area: Dynamic Links removal leaves email action link flow on obsolete domain
Likely root cause: Authentication emails open a dead/incorrect deep-link route after SDK migration.
Repair direction: Verifier checks migration to the supported successor and preservation of key behavior/data. Verify deployment metadata and end-to-end link/call behavior.Symptom
Authentication emails open a dead/incorrect deep-link route after SDK migration.
Why This Happens
The integration is locally correct for a resource that no longer exists or is no longer available to the account; only current service lifecycle data resolves it.
Common Wrong Fixes
- Changing local code without checking the current external contract.
- Retrying the same install, build, or API call with no version/source change.
- Applying a broad unsafe bypass when a narrow compatibility fix is available.
